GraphDistance

As of Version 10, all the functionality of the GraphUtilities package is built into the Wolfram System. >>

GraphDistance[g,i,j]
gives the distance from vertex i to vertex j in the graph g.

• GraphDistance functionality is now available in the built-in Wolfram Language function GraphDistance.
• To use GraphDistance, you first need to load the Graph Utilities Package using Needs["GraphUtilities`"].
• GraphDistance returns the graph distance from one vertex to another. Infinity is returned if no path exists from i to j. By default every edge is assumed to have an edge weight of 1.
• The following option can be used:
•  Weighted False specifies whether edge weight is to be used in calculating distance
